If the first Hobbit film was hampered by a treacherously slow introduction as the dwarves wooed Bilbo, here Jackson jumps right into the action — and make no mistake, this is an action movie above all else. The battles are visceral and physical, Jackson’s horror roots shining through in the movie’s fondness for decapitations, and while there’s no mistaking the aid of computer-generated imagery, the polish is so high it all comes together in a delirious frenzy.
